Efficient industrial production as propagated under the term industry 4.0 requires powerful and flexible sensors. Already today, the global market for machine vision solutions is huge (USD 9,10b in 2016) and still growing strong (predicted size of USD 15,46b until 2022). With automation moving forward, 2D is more and more replaced by 3D controls. Consequently, the 3D market is even growing faster (size of USD 1,37b in 2017 and predicted to have a size of USD 2,45b by 2022).
In industry, there exists an extensive range of very specific applications, for which today a variety of 3D sensor concepts exist. However, there is no solution for each and every problem and all sensor concepts turn out to have shortcomings.
Our patented light-field technology allows to build a new 3D sensor, which is small in size, auto-calibrated and robust to reflections for inline use at competitive cost.
It is particularly useful where small baselines are required, for example for the inspection of small metal parts such as electronic connectors or to control high precision welding processes or to navigate small and agile robots. It is made up of standard hardware components, i.e. an industrial camera, a main lens and, if necessary an active illumination projector, which are extended by a dedicated optical system (the K|Lens). Therefore, it can be easily adjusted to required use case parameters, such as working distance, region of interest and x/y/z precision.
